Electrical equipment box

Abstract

The present invention provides an electrical equipment box. A first opening chamber including a first sealing strip and a first door panel hook protrudingly provided with a first protrusion are arranged at the end of the door panel; a second protrusion and a third protrusion are arranged at the end of a first box plate; the first protrusion and the second protrusion are of a hook-shaped structure;the first protrusion is provided with a first contact curved surface; the second protrusion is provided with a second contact curved surface; the first contact curved surface abuts against the secondcontact curved surface; and the third protrusion is in elastic contact with the sealing strip to realize the sealing of the first box plate and the door panel. The hook-shaped structure of the firstprotrusion and the second protrusion plays the role of limiting the relative displacement between the first box plate and the door panel. The sealing method of the invention realizes sealing without the traditional hinge structure installed on the box door and the box body, reduces the number of parts and simplifies the installation process. The structure is simple and the installation is convenient.

Description

technical field [0001] The invention belongs to the field of rail vehicle electrical equipment, in particular to an electrical equipment box. Background technique [0002] With the expansion of city size and population increase, the problem of traffic congestion in the city has become more and more serious. Since urban rail transit has the advantages of being fast, safe, and does not occupy ground space, it is necessary to vigorously develop urban rail transit. Become an important way to solve the traffic problem in the city. [0003] With the development and progress of urban rail transit, it is difficult for the equipment box under the rail transit vehicle to meet the increasingly stringent vehicle counterweight requirements. Therefore, under the premise of ensuring the strength, the traditional electrical equipment box is installed on the box door. It is sealed with the dynamic hinge and static hinge structure on the box body. The traditional sealing method uses a large ...
